Accident Reconstruction – Litigation Support & Expert Witness

Expert Witness and Litigation Support

Explaining highly technical and complex topics to a lay audience, judge or jury, can be challenging. As expert witnesses, our role extends beyond determining what happened; we also must help attorneys and juries clearly understand how and why an event occurred. To support this objective, YA Group offers both physical and digital tools to visually communicate critical findings with precision and clarity.

Our Services:

Developing highly detailed forensic animations and digital trial exhibits using advanced photogrammetry and 3D technologies.

Producing accurately scaled physical models of accident scenes and vehicles using precision 3D printing.

Analyzing video footage from security, dash, and body‑worn cameras to identify key data including speed, impact locations, and traffic control information.

Using photogrammetry and 3D scans from site inspections to support and confirm video analysis findings.

Validating video findings with physics‑based simulation tools such as PC-Crash, HVE and Virtual Crash to ensure accuracy and reliability.

Physical Models

Physical models remain one of the most effective ways to help jurors understand the mechanics of an incident. Whether a single vehicle or a complete reconstruction of a complex scene, our graphics team produces models at a variety of scales to best suit our client’s needs. Using advanced 3D printing techniques, we deliver fast‑turnaround models without sacrificing detail or accuracy. Each model is developed from accident scene photographs, physical evidence, first responder data, and findings from on‑site inspections.

Digital Reconstructions & Photogrammetry

YA also leverages state‑of‑the‑art photogrammetry and 3D visualization technologies to create detailed forensic animations and trial exhibits. These digital reconstructions transform accident scene data into compelling, scientifically accurate visual presentations ideal for courtroom use.

Forensic Video Analysis

Our certified forensic video specialists (including LEVA‑trained analysts) use industry‑leading software to evaluate security footage, in‑car videos, and body‑worn camera recordings. The forensic video analysis enables us to extract critical details such as vehicle speed, impact points, timing, and traffic signal sequencing. To further support our findings, physics‑based simulation software such as PC-Crash, HVE and Virtual Crash to validate motion, trajectories, and event sequences.
